Types of lofts

Loft Conversions

Loft conversions are very popular in the UK since they take advantage of the empty space on your property's roof in to transforming it into a functional room, such as a bedroom, office, gym, or storage space.

A loft conversion in London will improve and add value to your property and you will also be eligible for a numerous of other benefits. However, the installation of a loft conversion is a complicated process due to the large amount of work involved and difficulty in finding the matching type of loft.
For example, when designing a loft conversion you will have to consider the variety of roof shapes, from almost flat to steeply pitched; arched or domed; single flat sheet or complex arrangement of slopes, gables and hips; or truncated to reduce the overall height.

The most popular styles of dormer conversions include:

a) Mansard

Mansard loft conversions, named after the 17th-century French Architect Francois Mansard. They are situated to the rear of the property, they have a flat roof, with the back wall sloping inwards at an angle of 72 degrees and windows are usually housed within small dormers. The steep slope may be also curved.

Mansard Loft Conversions

Mansards became very popular in London due to the benefit of maximising the loft space and the ability to make use of all roof space.
This type of loft conversion could be the preferred option in sensitive areas and / or where original framework of the property is the available option in order to maintain the property's character.
Generally Mansard owners prefer a flat room Mansard style due to it being the most cost effective. However, the majority of mansard loft conversions in clapham and around London will require planning permission due to the large changes to the roof shape and structure.

L-shaped mansard loft conversions can really open up the space and add even more value to your property.
An l-shaped mansard loft conversion works particularly well if you are converting the loft into an open-plan bedroom with en-suite.

Double mansard loft conversion

This type of loft conversion is similar to a normal mansard but also with a mansard to the front.

With a double Mansard loft conversion you will benefit from a larger square space since both sides of the roof will open, adding a Mansard onto both sides.
However, with this loft conversion option a complete change to both sides of the roof will occur. Hence, in some cases there may be restrictions on changing the front design of your roof, so even with planning permission it may be difficult to gain a double Mansard conversion.

b) Gambrel (curb, kerb)

A gambrel or gambrel roof is similar to that of a mansard roof, but usually has a symmetrical two-sided roof with two slopes on each side, with vertical gable ends instead of being hipped at the four corners of the building. The upper slope is positioned at a shallow angle, while the lower has a steep slope.
This design provides the advantages of a sloped roof while maximizing headroom inside the building's upper level and shortening the lower level.

c) Hipped roofs

Hip to Gable Loft Conversions

For the Hipped roofs, a hip end is the sloping end to a roof and a gable is the triangular section of wall which stands between two sloping roofs.
Keeping this in mind, you could consider between various types of Hipped roofs such as:

Hip to Gable

This loft conversion option is preferred for houses with a reasonably small internal volume using a smart solution to maximise their space.

This type of conversion increases the size of the loft space by changing the sloping side of the property to a flat gable end and allowing space for the staircase. It extends the roof's ridge line from the existing hips to the furthest vertical wall.
Similarly to the double mansards this type of loft conversion changes the outline of the roof, hence a planning permission could be required.

Hip or hipped

A hipped roof is sloped in two pairs of directions in contrast with the one pair of direction for a gable roof.

Cross hipped

Joining two or more hip roof sections together results in an L or T shape formation or any other number of different and more complex formations.

The most common hipped roof type is the hip to gable loft conversion which gives you a much larger living space in the existing loft area, allows you to gain the best staircase positioning, could even accommodate a shower-room and increase standing space.

d) Velux or roof-light loft conversions

Velux Loft Conversions

As velux are the leading window brand and manufacturer of the types of windows used in this loft conversion, velux loft conversions were named after them. It is one of the most cost effective way to convert a loft and it involves creating a roof with sloping window(s) pointing towards the sky fitting to the roof-line and leaving the original roof structure untouched. Therefore, planning permission is not generally required.

In this type of loft conversion velux windows are installed to the roof-line, hence no large alterations need to be made to the roof, while keeping the costs of the conversion lower.

e) Loft Conversion with Roof Terrace

Roof Terrace Loft Conversions

This type of loft conversion is ideal if you want to get your own terrace but you don't have any space around your property. Or perhaps you already have a balcony or terrace roof that you'd like to upgrade and make it into a special outdoor space that you can enjoy during the warmer months.
Whatever your choice you can convert your existing flat roof into the outdoor space you always wanted.

Roof terraces are more popular in areas with a large number of flats as space is difficult to find and gardens tend to be either small or dark, or both.

A Planning permission will be required for this type of conversion, but planning regulations have become more relaxed in relation to roof terraces.
